Paradyne 3616, 3615 manual Configuration Branch, Lamp Test, Selecting an Application Configuration

Operating the DSU

Lamp Test

The Lamp Test is a local test of the status indicators (LEDs) and liquid crystal display (LCD) on the DSU's control panel (both models). Any indicator that does not flash is not functional.

Note that if all LEDs are functioning, all the indicators on the Model 3615 DCP are flashing steadily. In a COMSPHERE 3000 Series Carrier, the indicators on the SDCP remain ON. The LCD on the DCP or SDCP alternately flashes solid blocks, moving from position to position on the display until the test is aborted.

Pressing any key except the key will stop the LCD portion of the Lamp Test and return you to the DSU Test menu so you can abort the test. Once aborted, the LCD and LEDs stop flashing.

Configuration Branch

The Configuration (Confg) branch allows you to configure or customize the DSU and its DBM to fit your site's requirements, to enter and change telephone numbers, and to specify the mode for viewing or editing configuration options.

Selecting an Application Configuration

The DSU is shipped from the factory with three common applications already configured. All you have to do is select the appropriate application and load the preset configuration into the unit. These configurations include:

•Synchronous Backup for a Control DualFlow DSU (SyBC) ± Sends user data over the DDS connection via the V.35 port, and configures the DBM for synchronous user-data transfer during Bandwidth on Demand or backup situations. This configuration also configures the DualFlow DSU to dial when DTR on the EIA-232 port transitions from inactive to active, and to disconnect when DTR transitions from active to inactive (DTRCallCon: Orig). Used for a control device.

•Synchronous Backup for a Tributary DualFlow DSU (SyBT) ± Sends user data over the DDS connection via the V.35 port, and configures the DBM for synchronous user-data transfer during Bandwidth on Demand or backup situations. This configuration also configures the DualFlow DSU to answer calls only when DTR on the EIA-232 port is active, and to disconnect when DTR transitions from active to inactive (DTRCallCon: Ansr). Used for a tributary device.

•Dial Diagnostics (DiDg) ± Sends user data over the DDS connection via the V.35 port, and configures the DBM for asynchronous router-management data and for disruptive diagnostics.

Select the appropriate configuration based upon how the unit will be used within your network. All configurations support simultaneous DDS and DBM connections. The difference is in how the DBM connection is used.

Refer to the Application Configurations in Appendix E for examples using these three configurations. Refer to the DSU's menu in Appendix A as you follow these steps.

.Procedure

1.Select Confg (Configuration branch).

2.Press the F1 key to select Opts (Configuration Options subbranch).

The Load from screen appears.

3.Press the or key to scroll the desired configuration into view.

NOTE

By referencing the menu in Appendix A, you will see that

pressing the key is often more efficient.

4.Make your selection: SyBC, SyBT, or DiDg, and press the function key (F1, F2, or F3) directly below the desired configuration.

The Edit/Save screen appears.
